Although not cheap, for it's combination of convenience, taste and light weight, freeze dried food is the only way to go if you want to carry more
than a few days worth of food.
Expedition Foods and UK bought Mountain House contents are made by European Freeze Dry, the European subsidiary of the US Mountain House company
so they are the same thing.
Both EF and MH come in proper big lads portions, are easy to prepare and taste very good.
Katadyn's "Trek'n'Eat" brand are not bad either but only come in 630ish kcal portions.

Katadyn has a £5 flat shipping rate to the UK.
You're right about Reiter, they're not the greatest.
I know nothing about Be-Well but you could glean an idea about who the manufacturers of the contents are by googling the EU food producers code.
I've had some good luck searching for bargains from US online outdoor retailers during sales but I'm not sure about the legality of importing these things .
I scored twelve large portion US MH meals plus postage two months ago for about half the price I would pay here in Europe.
Happy trails...torc.
